Textbox Control in a Repeater in ASP.Net

[Guest]

I am attempting to print out a table using a repeater in which one field is
updatable. Basically you would have a table of x number of rows and y number
of columns. However: only one field in each row will be updatable. My
thought was to build a repeater and then one of the <ItemTemplate> would be a
textbox where the user can update the values in each.

How would I go about in the code-behind to reference each textbox? My
texbox definintion is: <asp:Textbox ID="cID"......

Is an array created and I loop through the array? Just not sure how to
handle this.

Thanks for any help

why not loop thorugh the repeater item and find the control you want using
the control id and then set the readonly value as required.

i.e

for(int i = 0; i < repeater.Items.Count; i++)
{
TextBox tb = repeater.Items.FindControl("cID");
...
...
}

Thanks for the response.

Originally I thought I was doing something wrong: as I had the following
line:
foreach(RepeaterItem dataItem in rpRepeater.Items)

which was not bringing anything back. However: when I use your line as
well: the count is returned at 0 and the for loop exits immediately.

When viewing the page, I have upwards of 45 rows, so I know there are items.
What am I missing?

Thanks

NEvermind: your code was working. I had the ViewState=false which was
causing the issue in the backend.

Sorry for all the dumb questions ;-)

Thanks so much for the help though. I appreciaate it, but it was another
ID-10T error ;-)

For setting the value, use the ItemDataBound event:

private void Repeater1_ItemDataBound(object sender,
System.Web.UI.WebControls.RepeaterItemEventArgs e)
{
if ( e.Item.ItemType == ListItemType.Item )
{
TextBox myTextBox = (TextBox)e.Item.FindControl("TextBoxName");
myTextBox.Text = "Some Text"; // use "e.Item.DataItem" to get data from
a bound data source.
}
}


To read the user's changes:

foreach ( RepeaterItem item in Repeater1.Items )
{
if ( item.ItemType == ListItemType.Item)
{
TextBox myTextBox = (TextBox)e.Item.FindControl("TextBoxName");
// do something with "myTextBox.Text"
}
}
